Joe Cocker knows how to rock, man.
This is one of the most memorable live moments in music history, no doubt.
Beyond the undeniable quality of the song - so good that I have almost come to associate the piece with Cocker, instead of with the Beatles (which is quite a feat) - the way he handles himself on the stage is second-to-none. He's obviously gone insane for eight minutes, and it's results are perfect.
A question: do we think Cocker actually believed that he had an instrument in his hand the entire time? I'm not ruling it out....
